JOHN MILLER, OF BUFFALO, NEW YORK.

IMPROVEMENT IN COMBINED BEER FAUCET AND VENT.

Specification forming part of Letters Patent No. 42,676, dated May 10, 1864.

To all whom, it may concern.-

Be it known that l, JOHN MILLER, ofthe city of Buffalo, in the county of Erie and State of New York, have invented a new and Improved Beer-Faucet; and I do hereby declare that the following is a full and exact descrip; tion of the construction and operation thereof, reference bein g had to the accompanyingdrawings, making a part of this specification, in Which- Figure I is a section showing its several parts. Fig. 1I is an elevation of the vent.

Having reference to the drawings, A represents the main stem of the faucet. B represents a piston-cylinder, which rises vertically at right angles to the main stem, and B is a cap thereon. C is the discharge-nozzle. Dis a post rising from the main stem to support the operating-lever E.

The bore of the stem, which is represented at a', runs parallel with the body of the stem until it meets the abutment j', and then it rises vertically half an inch, (more or less,) and is capped with the flap-valve G, which valve is free to work on the top of the said bore and W thin the faucet.

H is the piston-head, and H piston-rod, which Works through the cap B.

I is a coil-spring, which surrounds the piston-rod, one end of which presses against the the capacity of the piston-cylinder, so that the cap B and the other end against the pistonplunge of the piston will cause the beer or liqhead H, and serves to press. and hold the pisuor to pass out under great pressure and proton down to its lowest position. duce a sparkling foam of theliquorin the glass.

Jis the bore or aperture which leads from What I claim as my invention in a beerthe piston-cylinder to the disehargenozzle, faucet is and K is a flap-valve on the end of said bore, 1. The piston-cylinder B, pistou H, and which is free to work on the end thereof and valves G and K, constructed and operating within the valvechamber K. substantially as herein described.

2. The vent-valve M, supported and opershown, and, passing over a pulley, P, on the post D, connects with the lever E, so that when the lever is raised it will pull on the cord and open the vent-valve M, and when the lever is lowered so as to slacken the cord the spring will act and close the vent-valve.

Vhen the piston is raised by means of the lever E, it liberates the valve G and opens the vent, as before described, so that the liquor will have a free flow from the cask. The How of the liquor will open both valves G and K. At the moment the piston begins to rise it will cause a suction, which will close the valve K and prevent a current of air from passing in through the dischargefnozzle to intercept the flow of the liquor. The tiow ofthe liquor will open the valve and fill the nozzle.

When the glass or vessel into which the liquor is drawn is nearly full, the piston is forced down. The moment it begins to descend the valve G closes and prevents any of the liquor which remains in the piston-cylinder from being forced back into the cask, while at the same time the downward plunge of the piston will force out all the liquor in the piston-cylinder through the discharge-nozzle into the glass, which will produce a beautiful foam of lthe liquor in the glass.

The discharge-nozzle is much smaller than L is a vent-plug, which is put into the head of the cask or` barrel. ated upon the spring N, in combination with M is a valve covering the vent-aperture l', i which valve is attached to the spring N, so that the spring will close the valve and hold it secure] y over the vent-aperture. This spring litnessesz is attached to and supported by the plug.

O is a cord attached to the said spring, as

a faucet, constructed as set forth.
